2mo PillHookCollects a flat 1% toll on the ETH leg of all swap forms (exact-in/exact-out, both directions) in a single deployer-pinned pool. Toll accumulates as ERC-6909 claims in the PoolManager and is withdrawable to a fixed vault address via permissionless collect(). The fee rate can only be lowered, never raised, by the deployer.

On sells of the configured "main" token it absorbs the sell at pool execution price from a secondary-token pot (shield, via beforeSwap delta). On buys it spends the pot to buy more main (pump, via nested swap in afterSwap). LP programs auto-harvest fees inside swaps, splitting into compound, buyback, burn, and recipient shares.

Fees range from 0.01% to 2.00% across four continuous regimes with no cliffs.

On sells of the designated main token, a pot absorbs a portion at the pool's exact execution price (shield, via beforeSwap delta). On buys, pot funds purchase more of the main token and deliver it to a configured recipient or burn address (pump, via afterSwap nested swap). Optionally manages an auto-compounding hook-held LP position whose fees are split between compounding, buyback, and burn.

Sells burn a fixed percentage of PXT and skim USDC at penalty rates, with an attribution rebate for sellers who identify themselves via attributeSell; buys are charged a USDC fee split between donation and marketing allocations.
